Hello Christian,

thanks for your constant improvement of ISIS. Could you implement the weighted summing of spectra also for echelle spectra? There I would find it even more useful, even though it might be a little more complex to program (equal weight for all orders of the same spectral image).
By the way, where can I find a list of the all the valid commands which can be used in the command line?

Regards, Martin
